Project OverviewProject Overview

Gridlock Avoidance System (G.A.S.)

ODU CS 410/411

presented by David Grant PM

Project GoalProject Goal

Our main goal is to develop a computer-based simulation model to mimic the behavior of the Hampton Roads Interstate System south of the Mercury Blvd. Interchange to the Battlefield Blvd. Interchange.

Project Sub-goalsProject Sub-goals

We intend to provide city planners and transportation professionals with results that describe their system’s operations at current and modified vehicle flow rates in two formats: statistical and graphical.

This tool is necessary to support the interstate highway system in Hampton Roads which is a critical element to the infrastructure of society in the area.

Project Sub-goals (cont.)Project Sub-goals (cont.)

Demonstration simulation of a small segment of the Hampton Roads interstate system for project validation and verification.

Market the project on a consultant basis (what ifs).

Completion by the end of the calendar year 2001

Y2K compliant software and hardware

Competitive AnalysisCompetitive Analysis

Competitors – Other Traffic Simulation products

Strengths – Currently not being used by the local

governments or VDOT Weaknesses

– Data must be in a usable format– Different localities maintain their data

differently

Evaluation MethodsEvaluation Methods

During Fall Semester 1998 and Spring Semester 1999, there will be regular status and brainstorming session of the group and sub-groups.

During the implementation and Completion phase we will use accepted SEI standards (formal and one-on-one peer reviews, Test Readiness Reviews, Team Advisory Groups for customer acceptance).
